Application led August 17,1909. lSerial No. 513289t To alt eti/omet 'may concern.' Y

Be it known that I, JAMs I. Woon, a citizen of the United States, residing at Salida,

in the county of Chaffee and State of Colorado,v have invented vcertain new and useful Improvements in Automatic Fuel-Cut-Oif Governors for Explosive-Engines, of which the following is a specification, reference being had to' the accompanying drawings.

This invention is an automatic fuel cutod governor for gasolene or other explosive engines.

The object of the invention -is to 'provide a gasolene or other fuel feeding 4means of an explosive engine with asimple and prac tical operating mechanism which will automatically stop' th'e supply of fuel when the.

engine runs too fast.

. With the above `and other objects in View,

the invention consists of the novel features of construction and the combination and arrangement of arts hereinafter fully described and cla1nied,.and illustrated in the other fuel is fed from a tank 2 or othersource of supply by means of a- -pumfp or equivalent device 3. The piston 4 o the puiup is actuated froml the-crank Shaft 5 of the engine by means of my improved automatic -iucl feeding and cut-ott governor which consists of an eccentric 6 fixed to the shaft 5 for rotation therewith and adapted to actuate a 'rod 7 which in turn actuates the piston rod 8 of the pump 4. As illus tinted, the pump rod 8 is actuated in -ono dil rection by a .coil spring t) and in the other direction by the rod 7, which lat-ter is slidably mounted inguide bearings l() and car- .ries an .anti-friction roller 12 to bear against the peripheryr of the eccentric 6.A The latter' is iii the forni of an open ring'having -at diametrically opposite points on one side surrounds one of the pins 14 an Afined between the outer side of-thje hub 15' the outer side of .the ring and d is ally o posite directions froma hub 15 suit- 5'5- ably xed to the shaft 5. Two radiall projecting guide pins 16 are also provi ed on the hub and bear against the side edge of the eccentric 6, as shown. A c0il.(spring 17 and the inner side offtlie eccentric .ring -6, whereby the latter is yieldably retainedin an eccentric position on the hub. Provided on thel eccentric ring 6 at a point diametricf 65- elly opposite .that .side on which the spring 17 is arranged, is a weight 18 which-'when the eccentric'rotates, is adapted to increase thev centrifugal action and cause the eccentric ring to vary its degree of eccentricity according to the s eed o the engine. In operation, w en the .engine is runnin atthe desired or normal speed thespring 1 holds the ring 6 eccentrically on the liu `15 and hence on the fly wheel or crank shaft 5,

so that as the latterv rotates theeccentric ring will cause the rod7 .to Abe reciprocated toactate the pump 4. When the s peed of the engine increases the weight 18 will cause the ring 6 to slide laterally on thel pins 14 I8,0

and assume a o sition 'concentric or more nearly concentric with. the shaft 5, thereby shortening 'the stroke of' the pump piston -and reducing the feed of fuel to the en ine.

When the speed of the engine drops bac to normal the spring17 returns-thefeccentric ring to its normal eccentric 'position'and the feed of the fuel .is therebymcreased Having tlius'described the invention what is claimed is:

' The combination w .i explosive' engine A and afuel' pump having 'a spring pressed 'ref :iprocatory piston, vof n hub-fixed to the engine shaft, aniopeneccentric ring inclos?Y ing saidl hub-and formed at diametrically 95 opposite points. .withopenings, 'a pair lof oppositely. disposed ins pro]ectmg radial y 4from thehub -an extending through 4,the openings inifsiid eccentric ring, a .'coil s rin upon one of said pins between the hu an 100 ring, a4 weight arm projecting radiallyfrom sed adjacent to saidjother pin, a secon -pair of oppositely disposed radially projecting pins.

is vcon- 60 arranged on the hub'in a plane at right sd slidably mounted rod and adapted to ed to engzge the edge of said ring, guides si upon the engine, a rod slidably mounted on Said guides and adapted to have one end4 sugo 'ed with the pump piston'rod, and an -antlriction roller upon the other end of angles to the lane vof the first mentioned Contact with said eccentrie'ring. 1o pins, the sec-on mentioned. pins being adapt- In testimony whereof I hereunto ulx 1n y gnature in the presence of two witnesses.
